Energy Efficiency and Conservation

Before investing in renewable energy sources, Decerna recommend that energy conservation and efficiency are first tackled. This can offer a cheap and effective way of reducing costs and carbon emissions as well as making it easier to meet the reduced demand with renewable energy.

There are many simple measures which organisations can take, including insulation measures, improving Building Management System (BMS) controls, changing lighting, upgrading equipment, improving glazing and educating building users.

Decerna can carry out energy efficiency audits of commercial and public buildings. This can range from giving simple measures for low and no-cost improvements, to detailed analysis of present heating systems, calculations of efficiency and advice on detailed works for substantial economic and carbon savings.

This expertise also feeds into our work on low carbon buildings.
